Why Processed FLY ASH? |
|
Several new and important technologies are being commercialized in the areas of fly ash beneficiation
and utilization to bring fly ash into conformance with current ASTM, IS & other world standard
specifications for use in concrete. As the fly ash utilization industry has matured, quality control, quality assurance, and improved product performance have incresingly
become important. Technologies have been commercialized to improve and assure fly ash quality for conventional concrete applications.
Also, fly ash utilization technologies have been developed to produce high performance concrete products.
Changes in boiler operations or alteration of air emissions control systems at power plants will alter the quality of fly ash produced. Factors that may impact fly ash
quality in this way include:
- A redution in the pozzolanic reactivity caused by increased proportion of coarse particles.
- The presence in the fly ash of excessive Loss on ignition (LOI)
- Chemical residuals from post-combustion emission control
